"WALL CONSTRUCTION.

Application filed April 16, 1925.

My invention relates to fire brick and wall constructions, and more particularly to the walls of tire chambers of furnaces, fire boxes, combustion chambers and boiler settings.

The object of the invention is to construct a fire brick wall so that it will withstand the heat to which a furnace wall is subjected.

This object I attain by using a certain form of brick, which can be so laid that the wall will withstand intense heat without distortion.

In the accompanying drawings:

Fig. 1 is a perspective view of a wall made in accordance with nay invention;

Fig. 2 is a front elevation of the wall;

Fig. 8 is a plan view of one course of bricks forming the wall;

Fig. a is a plan view of another course of bricks forming the wall;

Fig. 5 is a plan view of one of the bricks;

Fig. 6 is a plan view illustrating a corner of a wall;

Fig. 7 is a sectional elevation showing a wall with air vents;

Fig. 8 is a plan view of a grooved brick; and

Fig. 9 is a sectional view of the brick shown in Fig. 8.

The bricks a are made as shown in Fig. 5, having a plane in the form of a parallelogram, comprising parallel sides and parallel, angularly disposed ends, and being of the ordinary thickness of bricks used in furnace wall construction. The bricks are laid in courses, as shown clearly in Figs. 1 and 2.

In the course 1, the front bricks thereof are laid transversely of the. wall. Each side of greater lineal dimensions of each brick occupies a position at an angle in respect to the face of the wall, the ends forming the said face of the wall. At the back of the front row of bricks is a row of bricks 3, each one of which is laid with one of its sides abutting the rear ends of the front bricks 2, as illustrated in Fig. 1.

The next course a of bricks, forming the face of the wall, is laid transversely thereof, and at an angle of equal degree and opposite directional inclination with respect to the bricks of the other course, so that each brick 5 ofthe course l overlaps three of the bricks 2 of the lower course 1, with their ends for1n ing the face of the wall. A row of bricks 6 is laid above the bricks 3 and break joints with the bricks, as well as with the bricks 5, forming the front face of the wall.

Serial No. 23,555,

The next course 7 is shown as a bondin course. The bricks 8 of this cor ranged lengthwise with their sides mg the front face of the wall. the ends long at an angle directionally opposite to that of the angular seams of the con and breaking joints with the bricks i ofsaid course. The rear bricks 9 of this course 7 are laid transversely so as to overlap the ends of the face bricks of the lower courses and to extend entirely over the back bricks 6 of the lower course, making an effective bond, as the transverse joints are at an angle to the joints of the other courses.

In the course 10, the bricks are laid as in the course l, while, in the next course, the bricks are laid as in course 1. The bonding course 7 can be repeated as often as desired to strengthen the wall.

The corners of the wall are preferably made as shown on Fig. 6, in which half bricks 11 are used at the ends of each course.

In some cases, the bricks a, forming the wall, may have longitudinal grooves b, as in Figs. 8 and 9, to form air vents 12, which connect with an air space 13 in the wall, Fig. 7.

In some instances, the courses of the bricks may be laid as shown in Fig. 6, the

rear bricks of each course, with the exception of the bonding course, being of red bricks, which form part of the rear portion 14 of the wall.

I claim:

1. The combination in a furnace wall of a series of courses of bricks forming the wall, the bricks having parallel sides and angular ends; the bricks of one course being laid transversely side by side with their ends forming the face of the wall; the sides being at an angle to the face of the wall; a row of bricks arranged longitudinally to complete the thickness of the wall; another course of bricks being laid transversely opposite to the angle'of the other course and breaking joints with the bricks of said course, and a series of longitudinally arranged bricks filling out said course anda bonding course.

2. The combination in a furnace wall, of series of courses of bricks forming the wall, the bricks having parallel sides and angular ends, one course of bricks being laid transversely side by side with their ends forming the face of a wall, the sides being at an angle to the face of the wall, another course V-shaped of said bricks being laid transversely with the sides at an angle opposite totheangle of the other course and breaking joints with the bricks of said course; and a bonding course, in which-the sides of the bricks are arranged longitudinally to form the face of the wall, and rear bricks arranged transversely and breaking joints With the brick of the other courses.

3. Thecoinbination in a furnace Wall; a series of courses of bricks forming a wall, the bricks having parallel sides and angular ends, one course of bricks being laidtrans versely side by side with their ends forming the frontface of the Wall, the sides being at !5 an angle to the face of the Wall; a series of bricks arranged longitudinally and forming the rear face ofthe wall; another course of bricks being laid transversely With the sides at an angle opposite to the angle of the other course, and breaking joints With the bricksof said course; a series of bricks arranged longitudinally in said course forming the rear face of the Wall; and a bonded course in Which the sides of the bricks are arranged longitudinally to form the front face of the Wall, and the rear bricks arranged transversely and breaking joints with bricks of the other course.
